There are three key points you have to bear in mind:
Quality and Efficiency.
Most of these factors depend on what kind of software you use and whether you want to deal with Apple's default player (iTunes) or maybe you might want to seek alternatives to fit all your specific preferences. No matter what you give your priorities to – here's everything you need to know to transfer your music from Mac to iPhone and get ready for listening and enjoying music.
Since you are interested in a way to transfer music stored on your Mac to your iPhone, you probably don't use streaming services as such, for you already have the songs you like and would like to just have them on your device. If you aren't keen on making choices and are OK to go with the flow or just happen to like iTunes – well, then you should use iTunes. It's a great service if you tend to buy music - after you pay for it, your purchased music will instantly appear on all your Apple devices because they synchronize.
Search, pick and buy music (sometimes there's also free music so keep an eye for special offers).
Wait till it appears on your iPhone in Music App, but you should make sure you have chosen the option of instant downloading for your purchases, otherwise, you can only stream it from iCloud).
How to transfer music previously purchased to iPhone and how to transfer music stored on your Mac to iPhone.
Connect your iPhone to Mac.
Scan your iPhone for media files.
If the scan doesn't find all necessary music you can add some manually (Drag & Drop the files, or open the folder in iTunes and choose Add to Library).
Transfer your music to iPhone.
Provided that you already have your music collection you should consider using iTunes Match. This app scans your local music library on your Mac and adds some particular tracks (by artist and name) to your iCloud storage. Later you can open your Library in Music App on iPhone, pick a track and tick the option of storing the song on your device by tapping near the selected track, otherwise, you will only be able to stream without being able to play the song offline. Not all music is available on iTunes though. You have to bear in mind that some tracks, for instance on SoundCloud, are even available for download.
All in all, iTunes is an excellent tool if your like to limit yourself to music purchased on iTunes and don't crave for much more. This process is also time-consuming because you have to perform too many actions and deal with too elaborate settings just to make sure that the music is on your iPhone.
